For holding the bolt 23 in its locking position, as shown in solid lines in Fig. 1, I have provided a cam 31 upon the upper face of the body 10, the cam in the construction shown being arranged concentrically about the axis of, the bolt 23. The inclination of the cam 31 and the position of the cam with respect to the bolt are such that when the bolt is forced up the cam to its operative position, as shown in Fig. 1, the bolt 23 and collar 24- are wedged tightly between the cam and the plate 22 of the housing, in which position the bolt is held by friction securely in place.

While I prefer to employ the construction as here shown, it will be understood that I do not wish to limit myself to details of such construction, except so far as such details are specifically claimed, inasmuch as it is evident that various changes may be made without departing from the spirit of my invention.

I claim:

1. A hose coupler lock for preventing disengagement of mating couplers comprising a bolt pivotally mounted on one of the coupler members in position to be moved into engagement with the other coupler member for preventing rocking of one member about a transverse axis with respect to the other member, the portion or" the second coupler member with which the bolt is engaged being formed to engage the bolt with a continuously increasing pressure as the bolt is moved to locking position for preventing its displacement from locking position.

2. A hose coupler lock for preventing disengagement of mating couplers comprising a bolt pivotally mounted on one of the coupler members in position to be swung substantially horizontally into close proximity to the other coupler member for preventing rocking of one member about a transverse axis with respect to the other member, and a cam underlying the path of the bolt as it swings into operative locking position adaptedto engage the bolt with an increasing pressure as the bolt is moved to locking position to prevent its displacement from locking position.

3. A hose coupler lock for preventing disengagement of mating couplers comprising a bolt pivotally mounted on one of the coupler members in position to be swung substantially horizontally into close proximity to the other coupler member for preventing rocking of one member about a transverseaxis with respect to the other member, means serving by friction to hold the bolt from swinging idly, and other means adapted by engagement with the bolt at the end of its movement into operative locking position normally to prevent displacement of the bolt from its locking position.

a. A hose coupler lock for preventing dis engagement of mating couplers comprising a bolt pivotally mounted on one of the coupler members in position to be swung substantially into close proximity to the other coupler member for preventing rocking of one member about a transverse axis with respect to the other member, means serving by friction to hold the bolt from swinging idly, and a cam adapted at the end of the movement of the bolt into operative locking position normally to prevent displacement of the bolt from its locking position.

5. A hose coupler lock for preventing disengagement of mating couplers, comprising a bolt pivotally mounted at an intermediate point on one of the coupler members in po sition to have one end swung into close proximity to the other coupler member for preventing rocking of one member about a transverse axis with respect to the other member, and a cam underlying the other end of the bolt adapted to engage the bolt with a pressure which increases as the bolt is swung to operative position to hold the bolt normally by friction from displacement from operative position. I

6. A hose coupler lock for preventing disengagement of mating couplers comprising a bolt pivotally mounted on a vertical axis on the upper face of the body of one of the coupler members in position to swung into close proximity to the upper face of the arm of the other coupler member for preventing the members from rocking about a horizontal axis with respect to each other, and yielding means adapted by pressure on the bolt normally to hold the bolt against swinging idly.

7. A hose coupler lock for preventing disengagement of mating couplers comprising a bolt pivotally mounted on a vertical axis on the upper face of the body of one of the coupler members in position to swing into close proximity to the upper face of the arm of the other coupler member for preventing the members from rocking about a horizontal axis with respect to each other, and a cam on the body underlying the bolt adapted by engagement with the bolt at the end of the swing of the bolt to operative locking position to hold the bolt normally by friction from displacement from its operative position.

8. A hose coupler lock for preventing disengagement of mating couplers comprising a bolt pivotally mounted 011 a vertical axis on the upper face of the body of one of the coupler members in position to swing into close proximity to the upper face of the arm of the other coupler member for preventing the members from rocking about position to hold the bolt normally by fric-- tion from displacement from operative position.

9. A hose coupler lock for preventing dis-- engagement of mating couplers, comprising a housing on the upper face of the body of one of the coupler members, abolt extending through said housing, anda pin passing through aligned openings in the housing,the bolt. and the body, for mounting the bolt pivotally in position to swing into close proximity to the other coupler member for preventing the members from rocking about a horizontal axis with respect to each other.

10. A hose coupler lock for preventing disengagement of mating couplers, comprising a housing on the upper face of the body of one of the coupler members, a bolt .ex tending through said housing, a pin passing through aligned openings in the housing, the bolt, and the body, for mounting the bolt pivotally in position to swing into close proximity to the other coupler member for preventing the members from rocking about a horizontal axis with respect to each other, and a second pin carried by saidhousing extending across the end of the first named pin for preventing withdrawal thereof. a

11. A hose coupler lock for preventing disengagement of mating couplers, comprising ahousing on the upper face of the body of one of the coupler members, a bolt extending through said housing, a pin passing through aligned openings in the upper wall of the housing and the bolt for mounting the bolt pivotally in position to swing into close proximity to the other coupler member for preventing the members from rocking about a horizontal axis with respect to each other, and a spring mounted on said pin between the bolt and the upper wall portion of the housing for pressing the bolt yieldingly into frictional engagement with the body.

12. A hose coupler lock for preventing disengagement of mating couplers, comprising ahousing on the upper face of the body of one of the coupler members, a bolt extending through said housing, a vertically disposed pin upon which said bolt is pivotally mounted within said housing, and a spring washer mounted upon said pin between the bolt and the upper wall of the housing for pressing the bolt yieldingly against the body for preventing the bolt from swinging idly.
